Staff of the Department of Thermophysics is involved in the development of new innovative class of the testing methods transient methods for measuring of the thermophysical properties of materials. Principle of this class of methods is based on generation of a small heat disturbance inside a specimen and the measuring of the temperature response. Methods are included into this class where measuring probes are embedded into the material thus surface interfering effects are suppressed. Table 1 gives an overview of the basic experimental arrangement of the transient methods.

Table 1.: Transient methods and the corresponding parameters that can be determined by particular method. Theory and the methodology of transient methods that are accompained with info logo were worked out in our department.
